Hey there! The game currently doesn't have rollback implemented, however we are planning to support it in the near future. We'll be refactoring the framework codebase during 2021 and rollback is planned to be added during that period.
Ah I'm glad to hear it! Also I'm not sure how practical it is to implement since I don't really know much about coding, but it would be pretty cool to be able to set controls to custom keybinds.
Also I couldn't tell for sure, but did Brym's design get any slight changes? Part of me feels like there's a few small differences from his design in the last update. I still haven't played through the entirety of this update, so was Garreth the only visually updated character?
The control scheme we're using, as well as many other interface navigation patterns, are already very similar if not directly borrowed from Ren'Py's handling for the sake of uniformity and player ease of use. So while we may add the option to setup custom controls in the future (Godot offers easy ways to do that internally), it's not a priority for us at the moment.
We are continuing to implement new sprites as they get made, bit by bit, and yes, currently most of the work is going into making custom expressions for Garreth and Brym as well as Yarin's side portraits.
